Abstract

A process for the preparation of triethyl dimethyl siloxalane is disclosed. The process comprises admixing octamethylcyclotetrasiloxane with triethyl aluminum, optionally in the presence of an inert hydrocarbon solvent, at a temperature of 170 DEG -250 DEG C. for a period of at least 10 minutes. The molar ratio of triethyl aluminum to octamethylcyclotetrasiloxane is at least 3.9:1 and preferably 3.9-4.5:1. The siloxalane may be used as a co-catalyst in the polymerization of ethylene and/or other alpha-olefins.
